Yes planting it deeper is the way to go. The plant will be much happier.
I do this and repot into the same pot.This is also an opportunity to use fresh mix as the old mix is probably exhausted.

Hi, Lisa:

Do a search of this forum using "neck" or "necky."

When you repot, make sure you gently scrape the neck so the tissue shows. Roots will grow from the scraped places. And do like Andrew says and plant it deep (up to the bottom row of leaves) and back in the same pot.

You may also have to experiment with different lighting. I've had a couple plants do that, and it wasn't just the sheeding of old leaves; they weren't getting enough light and the stem itself kept growing taller and taller, not just the leaves reaching up. Be careful though, too much light and the plant will stop growing for months.

Seems that plants are overdue to be repotted, that's it.
